If you wanna learn Japanese, don't watch subs because you're paying all your attention on them, instead of what the characters are saying.
I watched this video 4 months ago and every since then I've dropped subs, and I understand Japanese a lot better now that when it comes to SoL anime I don't need to look up words anymore, but when I do it adds to my Japanese vocabulary.

The first day of ditching subs, the first couple of words I learned through comprehensible input were
>namimonowhen a character was visibly thirsy
>gyunyuuwhen a character poured a glass of milk
>netsuwhen a character had fever
>tsumetaiwhen characters were talking about wanting something cold to eat.
I would've never picked these up if I was watching subbed.
